Willans MX-5 4-point Road and FIA Harness: FIA approved to FIA 8854-98 for Road and Competition Use. 4-point MX-5 specific harness suitable and approved for Road and Track use. These MX-5 harnesses have shorter shoulder straps designed to wrap around a roll bar or harness bar, they are ideal for use in your MX-5 if used on the road or for track days.
As standard they feature shoulder straps manufactured to the correct length ready to wrap around your roll bar or harness bar, the lap strap adjusters are reversed to provide tensioning of the lap strap by pulling downwards away from the central buckle. Lap straps have Snap Hook fixings and eyebolts are supplied that fix to the original seatbelt mounting points in the car.
A harness bar manufactured specifically for the MX-5 can be supplied if required. Please use dropdowns to order.
Patented lightweight composite Rotary Buckle finished in satin black with a black Willans badge as standard; the badge (not the buckle) can be upgraded to Signature Red or Blue.
Please note that the Willans light weight (176 gram) quick release buckle is fixed to the left-hand lap strap on the drivers’ side (UK RHD vehicles) and the right-hand lap strap on the passengers’ side (UK RHD vehicles) With this configuration when the buckle is released it goes towards the centre of the car rather than the door. If you are ordering two harnesses, we will always supply one harness with a buckle attached to the left-hand lap strap and one harness with a buckle attached to the right-hand lap strap. If you are ordering a single harness, please confirm whether it is for the driver or passenger side (using the dropdown menu above) and we will supply a harness with the rotary buckle fixed to the appropriate side.
Steel adjusters to shoulder and lap straps can be upgraded to Willans Aluminum Adjusters if required. Shoulder Straps are all 3 inch (75mm) wide. Lap straps are 2 inch (50mm) as standard with the option of 3 inch (75mm). We recommend the 2-inch lap straps for the MX-5. Signature range includes additional colours and the option of the Historic Willans Label if required. Stitching thread is self-colour (same as harness colour) unless upgraded to a Signature colour using the dropdowns on the page. Shoulder pads are available in Black, Blue or Red only with Modern or Historic Labels. All straps are fully adjustable. Superb Willans quality throughout. Manufactured in the UK. A free Safety Hammer is included with every order.
